	The Winter/Spring 1989 issue of the INGRES Connection newletter
	has an interesting technical suggestion that apparently does 
	not seem to work. It says, 

	"Any INGRES executable can be pointed to a database different
	from the one originally used for development. For example, if
	you created the application executable, newapp, while using a 
	database called testdb, that database is the one opened when you
	run newapp. To run the same application executable against another
	database (say fulldb), execute the command newapp -d fulldb."

	In other words, if I had a .qc program in which I open a database
	(say, ## ingres testdb), I should be able to replace testdb at run
	time with some other database by using the -d flag. Well, it looks
	like there's something more to it than what the newsletter suggests.
	Any ideas?

	P.S.: Of course, one can use an equel/c variable as the database
	      name, and pass in the name at run time as an argument.
